The Carter Burden Network (CBN) is an New York City senior services agency, providing vital meal programs for low-income, minority seniors, age 60 and over. In 2016, CBN formed a community-academic partnership with The Rockefeller University (RU) and Clinical Directors Network (CDN) to conduct a Healthy Aging pilot study and found that 84% of participants had high blood pressure, with up to 27% "uncontrolled" using age-adjusted criteria. High blood pressure is a modifiable risk for cardiovascular disease, and has been readily improved in controlled trials by replacement of a typical Western diet with the Dietary Approaches to Stop Hypertension (DASH) diet. The DASH diet has been proven to meaningfully reduce blood pressure in as little as 14 days. However, the DASH diet has not been tested in seniors, in the setting of senior centers. Many seniors attending CBN centers receive close to 40% of their daily nutrition through congregate meals served there. This study tests the effectiveness of implementing the DASH-diet through modification of congregate meals at CBN senior centers to align with DASH, while providing educational and behavioral support, including home self-monitoring of blood pressure, to improve self-efficacy related to blood pressure management. The primary outcome is the change in systolic blood pressure.
The Carter Burden Network (CBN) is an New York City senior services agency, providing vital meal programs for low-income, minority seniors, age 60 and over. Its four senior centers serve 300,000 meals annually through congregate breakfasts and lunches, and home-delivered meals. In 2016, CBN formed a community-academic partnership with The Rockefeller University (RU) and Clinical Directors Network (CDN) to conduct a Healthy Aging pilot study at two of its East Harlem sites, finding that 84% of participants had high blood pressure, with up to 27% "uncontrolled" by age-adjusted criteria. Hypertension continues to be a significant, modifiable, but poorly-controlled contributor to morbidity and mortality from cardiovascular disease (CVD), contributing to stroke, heart attack, renal failure, and cognitive decline, increasing healthcare costs and causing loss of function, independence, and quality of life. Replacement of a typical Western diet with the Dietary Approaches to Stop Hypertension (DASH) diet has been proven to reduce blood pressure in i hypertensive individuals, and individuals with normal blood pressure in as little as 14 days. However, approaches to effective implementation of the DASH diet are untested in community-living seniors. To address the high cardiovascular risk of uncontrolled hypertension among seniors and introduce innovation into its nutritional program, CBN, RU and CDN designed this two year project to test a DASH-diet-based multi-component intervention to lower blood pressure in two of its senior centers, serving low-income and/or minority seniors. The intervention includes health education, participant input into menu design, redesign of current congregate meals menus to make them with DASH-aligned menus, and home-self monitoring of blood pressure with educational and social support. The primary outcome will be the change in mean systolic blood pressure, measured by health professionals one month after full DASH implementation, compared to baseline. Secondary outcomes include the change in the percentage of seniors with blood pressure in the range of "controlled" by Joint National Committee 8 (JNC-8) guidelines, and the change in blood pressure at three months and at six months. To optimize acceptance of the changes to menu and recipes, clients will be engaged and provide feedback during the design, implementation and conduct phases of the study. Dietary changes will be planned to incorporate client preferences. Clients will provide feedback weekly on menu acceptability referencing a simple smiley face Likert scale. Educational programs will consist of a series of sessions covering nutritional education including recipes and cooking demonstrations, blood pressure information and training in home self-monitoring with a study-provided blue-tooth enabled Omron 10 device, and information to enhance medication adherence. Participants will have pulse, blood pressure, weight, and behavioral aspects of self-efficacy assessed at baseline, and at Months 1, 3, and 6 of after DASH implementation. Surveys to assess quality of life, food frequency (for compliance with DASH-aligned eating outside of congregate meals), menu satisfaction, medication adherence, and other risks relevant to blood pressure management will be assessed at the same Month 0,1,3,6 time points).

On a programmatic level, congregate meal menus and recipes have been adapted to align with DASH eating. The changes, which include the introduction of additional servings of fruits, vegetables, seeds, grains, replacement of simple or processed carbohydrates with healthier alternatives, introduction of more fish, reduction in added salt, and replacement of animal fats and butter with olive oil, will be phased-in in stages over 6 weeks, concurrent with the start up the study's educational programs addressing nutrition, BP, and medication adherence. The fully DASH-aligned menus will begin by week 7. The dietary intervention affects all seniors eating congregate meals at the center, not only those enrolled in this protocol to study the impact of DASH implementation.
At baseline (Month 0), and at Months 1, 3, and 6 after the full implementation of the DASH aligned congregate meals, participants will have blood pressure measured by professionals, on-site at the senior center, following established standard procedures. They will receive verbal and written information about their blood pressure results, and encouragement to share the results with their providers.
Provision of personal Omron 10 home blood pressure monitoring device, training in proper use, and schedule for home self monitoring of BP over the course of the study.
One required educational session with the community pharmacist to learn about medication adherence strategies
One required educational session to review the elements of the DASH eating plan, how to overcome barriers to healthy eating, recipes, cooking demonstrations and materials for household members.

Change in Systolic Blood Pressure
Change in the mean of clients' systolic blood pressure measured at on-site assessments, reported in millimeters of Mercury (mm Hg).
Time frame: One month after implementation of the DASH-aligned congregate meals, compared to Baseline measurement (Month 0) before implementation of dietary or behavioral interventions
Change in Proportion of individuals with Blood Pressure is in the "controlled" range
The proportion of individuals who blood pressure is within the range "controlled" according to 8th Joint National Committee (JNC-8) guidelines, which for individuals age \>60 years, is systolic blood pressure \<150 mm Hg, and diastolic blood pressure \<90 mm Hg.
Time frame: One month after implementation of the DASH aligned congregate meals, compared to Baseline measurement (Month 0) before implementation of dietary or behavioral interventions
Sustainability of Change in Mean Systolic Blood Pressure at 3 months
Change in the mean of clients' systolic blood pressure measured at on-site assessments, reported in millimeters of Mercury (mm Hg)
Time frame: Month 3 after implementation of DASH meals, compared to Baseline (Month 0), before implementation of any dietary or behavioral changes
Sustainability of Change in Mean Systolic Blood Pressure at 6 months
Change in the mean of clients' systolic blood pressure measured at on-site assessments, reported in millimeters of Mercury (mmHg)
Time frame: Month 6 after full implementation of DASH meals, compared to Baseline (Month 0), before implementation of any dietary or behavioral changes
Enhanced self efficacy - self monitoring
Mean frequency of home blood pressure self-monitoring (number of measurements/week)
Time frame: up to Month 1
Cognitive and behavioral change - change in medication adherence self-efficacy
Change in mean score on Medication Adherence Self-Efficacy Scale (MASES-R) - this survey/scale asks participants how confident they are they can adhere to prescribed medications in 15 different settings that challenge adherence; responses are captured on a 4 point scale from 1-not at all sure, 2-a little sure, 3-fairly sure, and 4-extremely sure. Higher scores are better.
Time frame: 1 Month after full implementation of dietary changes, compared to Baseline measure
Client acceptance of meals
Mean Likert scale score (smiley card) score for DASH-aligned meals; Clients (participants) complete a meal evaluation card once a week, to reflect acceptance of recent menu offerings. The card asks, "Overall, How were the meals this week?" and asks the participant to rate the meals using a 5-point rating scale that ranges from unacceptable meals represented by a deeply frowning red face (1), through intermediates of a mildly frowning orange face (2), neutral expression yellow face (3), slightly smiling light green face (4), to a highly acceptable meal represented by a broadly smiling dark green face (5). Higher scores are better than lower values.
Time frame: 1 month after full implementation of dietary changes, compared to Baseline before implementation of any dietary or behavioral changes
DASH-concordance of meals
This measure reflects to what degree the meals as served during the intervention, were DASH-aligned, according to the recommendations of the DASH eating adapted for the designed study menus. This concordance is expressed as the number of the 8 food group requirements satisfied (defined in the DASH eating plan and adapted for the study menus) by the meals as provided. The DASH eating plan identifies 8 groups: 1-Grains, 2-vegetables, 3-fruits, 4-fat-free/low fat milk and milk products, 5-lean meats, poultry and fish, 6-nuts, seeds and legumes, 7-fats and oils, 8-sweets and added sugar. The higher the score, the more DASH-concordant the meal. This outcome will report the mean daily meal DASH-concordance, e.g." 7.5 food group requirements satisfied." For components that allow for weekly requirements rather than daily requirements, (e.g. nuts/seeds) the score for the week (requirement satisfied - yes/no) will be applied to each day within that week.
Time frame: During the first month of full implementation of dietary changes, compared to Baseline before implementation of any dietary or behavioral changes
